Acoustical engineering is the branch of engineering dealing with sound and vibration. It is closely related to acoustics, the science of sound and vibration. Acoustical engineers are typically concerned with:

• how to reduce unwanted sounds
• how to make useful sounds
• using sound as an indication of some other physical property

The art of reducing unwanted sounds is called noise control. Noise control engineers work with engineers in most industries to ensure that their products and processes are quiet.

The art of producing useful sounds includes the use of ultrasound for medical diagnosis, sonar and of course sound reproduction.
